Re: isset or ! isset what is my problem?

Actually this has nothing to do with rows. I'm just trying to substitute a value when a query returns an empty value. On Jan 3, 2006, at 5:24 AM, El Bekko wrote:

I'm building a URL based on data extracted from mySQL and I want the text space.gif used as my default value should the variable $picture by NULL. The results of the code below kick back a value for $picture when it is set in the database, but ignores the space.gif if the database result is empty. If I flip the test from ! isset to isset then I get the space.gif for each result. I've had no luck searching out an answer.

Seeing as you're querying, use mysql_num_rows() to check. --PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
